AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
840 PM CDT THU APR 16 2015

.UPDATE...
LOWERED RAIN CHANCES/TSTMS...ALONG WITH LOW TEMPS...FOR THE REMAINDER
OF TONIGHT. ALSO ADDED PATCHY FOG EARLY IN THE MORNING.

.DISCUSSION...
THE AIR MASS ACROSS THE AREA HAS DEFINITELY BEEN WORKED OVER BY THE
CONVECTION FROM EARLIER TODAY...AS EVIDENCED BY PRECIP DIMINISHING
RAPIDLY ACROSS CNTRL AL. LITTLE IF ANY OF THIS RAIN HAS BEEN ABLE TO
MOVE N OVER THE PAST FEW HRS...AND THIS TREND IS NOT XPCTED TO
CHANGE MUCH HEADING INTO THE LATE EVENING/OVERNIGHT HRS. ANOTHER
UPPER DISTURBANCE IS MAKING ITS WAY NEWD ACROSS THE REGION...AND THIS
FEATURE COULD RESULT IN A FEW MORE SHOWERS/EMBEDDED TSTMS OVERNIGHT.
THE PROB THOUGH HAS DECREASED...ESPECIALLY WITH LOCAL/MESO ANALYSIS
SUGGESTING A WEDGE FRONT LIKE BOUNDARY PUSHING SWWD THROUGH THE AREA
WITHIN THE LAST SEVERAL HRS. LIKEWISE...RAIN CHANCES/TSTMS HAVE BEEN
LOWERED FOR THE REMAINDER OF TONIGHT. IN FACT...THE THREAT FOR ANY
LINGERING TSTMS MAY ONLY EXISTS FOR A COUPLE OF MORE HRS. PATCHY FOG
WAS ALSO ADDED INTO THE FORECAST FOR THE EARLY MORNING PERIOD GIVEN
THE POTENTIAL LACK OF PRECIP AND A FAIRLY SATURATED GROUND. TEMPS
OVERNIGHT HAVE ALSO BEEN LOWERED A FEW DEGREES...GIVEN SOME LOCATIONS
WERE ALREADY AT/NEAR THEIR FORECASTED MINS. SOME PERSISTENT CLOUD
COVER/SE FETCH INTO THE OVERNIGHT HRS THOUGH MAY LIMIT TEMP TRENDS
FROM FALLING MUCH MORE FOR THE REMAINDER OF THIS EVENING.

A MIX OF MVFR/IFR WEATHER WILL PREVAIL ACROSS THE AREA FOR MUCH OF
THE FORECAST PERIOD. A SE FETCH WILL CONTINUE ACROSS THE REGION...

MUCH OF THE OVERNIGHT. ALONG WITH THE LOWER CIGS...PERIODS OF LIGHT
SHOWERS AND/OR FOG WILL RESULT IN REDUCED VIS VALUES TOO. HAVE ENDED
A MENTION OF SHOWERS AFTER DAYBREAK FRI...WITH CONFIDENCE NOT HIGH
ENOUGH TO CONTINUE THEM. WITH LIMITED DAYTIME HEATING AND ATMOSPHERE
